Rare
Under 5% of wildlife watchers report a Plum Beetle sighting in Vienna on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 760th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Plum Beetle in Vienna on a given day, against under 5% in June to March, the lowest months.
Among the best
Of the 3 cities where we can rate Plum Beetle sightings, Vienna ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in London (United Kingdom, under 5%).
Same family: Cerambycidae
The closest relatives of the Plum Beetle that you can see in Vienna (family Cerambycidae, Longhorn Beetles) are Alpine Longhorn Rosalia (about 10%), Common Grammoptera (about 10%) and Dorcadion aethiops (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Plum Beetle is recorded against all the insects logged in Vienna (14 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
